I'm replacing freeze plugs in a non performance 318, they'll be the usual brass or bronze or whatever they are now.
what if any sealant should I put on them? some sort of locktite? which one?

Permatex Form-A-Gasket.
They make 2 kinds, one that sets up hard and one that doesn't so use the one that fully dries. Clean the heck out of the openings and then wipe a little sealer in the hole and drive the plug home.
Lots of people stick these in dry and never have an issue. My experience is if one does leak it's always the toughest one to get to.

What Tater said ... plus maybe even some RTV. They tend to slide-in EZier using some sort of "sealer".

Permatex "brown death", the only thing it's good for.

Another vote for Permatex #1 (gets hard) & b sure & get freeze plugs that are deep (good ole Dormans) or brass
Permatex Form-A-Gasket #1 (fully hardening version) - I just installed a full set of brass deep-cup freeze plugs in the block + heads of a Magnum 5.9 motor and no leaks or issues. While you are at it, if this is a used motor, make sure that you check/clean out the water galleries of crud that builds up in the block with use.
